SPECIFICATION forming part of Letters Patent No. 639,487, dated December 19, 1899. Application filed April 14, 1899. Serial No. 713,028. (No model.)

To aZZ whom it may concern:

Be it known that I, ABRAHAM L. YATES, a citizen of the United States, residing at Niagara Falls,in the county of Niagara and State of New York, have invented certain new and useful Improvements in Indexed Books; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as .will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to indexed books; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a perspective view of the book with a portion of its cover removed and some of its pages turned up. Fig. 2 is a plan view of one of the detachable pages of the book.

A is the index-page of the book, which is preferably its first page.

B are the permanent blank or copy. pages of the book. The first blank page B under the index-page A is provided with anextension or tab b at its right-hand upper corner, and the remaining pages B are provided with similar extensions or tabs 6, arranged vertically under the first extension or tab and in a stepped progression. Each extension or tab is provided with a separate indication or mark-such as a numeral, letter, blank space, or symbol--to distinguish its page from the other similar pages, and the index-pageA is provided at b with similar indications or marks-such as numerals, letters, blank spaces, or symbols-40 correspond with those on the tabs or extensions and preferably arranged horizontally in line with them.

The index-page A is ruled with horizontal and vertical lines according to the purpose for which the book is to be used. As shown, the book is arranged to be used as a bill and account book; but it may be used for other purposes, such as a letter-book or a doctors prescription-book.

O are pages interleaved between the blank pages B and provided with a row of perforations 0, so that the greater portion of each page G can easily be detached and removed from the book. The pages of the book are all bound up together and are provided with a cover D. The pages B and O are preferably arranged in pairs; but, if desired, two or more similar pages 0 can be arranged next to each page B to which they may pertain, instead of a single page C. The pages Ohave no tabs or extensions and are ruledoff and printed like ordinary bill-heads or letter-heads or 0th erwise according to the purpose of the book.

E is a removable sheet of carbon-paper, which is placed loosely between any two pages B and G when the book is used, so that a copy of the matter written upon any perma= n'ent page C is formed upon the detachable page B to which it pertains.

WVhen the book is used as a billand account book, the name of each customer to whom goods are sold is entered on the index-page and the amount of his bill in the column marked Dr. If he pays his bill in part, the part paid is entered in the column marked Or. and the balance in the column marked Bal. The bill itself is written on the page G, and is copied by the carbon-paper onto the page B, which is marked to correspond with the mark on the index-page and the entry on the index-page is in line with the mark on the page B pertaining to it. The bill on the page C is detached and given to the customer, and the copy of the bill on page B remains permanently in the book with the index.

What I claim is- 1. In an indexed book, the combination, with a series of permanent pages provided with distinguishing marks upon extensions or tabs arranged in a stepped progression, of detachable pages arranged between the said permanent pages, and a single superposed index-page bound up with all the said pages and marked to correspond with the said permanent pages, the said detachable pages and index-page being arranged so as not to cover the said extension or tabs, substantially as set forth.

2. In an indexed book, the combination,

with a series of permanent pages provided with distinguishing marks upon extensions or tabs arranged in a stepped progression, of a series of detachable pages arranged in alter: In testimony whereof I affix my signature nation With the said permanent pages, and a in presence of two Witnesses. single superposed index-page bound up with ABRAHAM L YATFS all the said pages and marked to correspond with the said permanent pages at a series of WVitnesses: points in line with the marks on the said ex- HERBERT W.
